[Coco] CoCo temperature monitoring

[Mark Marlette]

Bob,

Other than resolution being poor, you might want to consider scaling  
the value to a range. Better to use modern technology, thermistors are  
not.

Go with a DALLAS product or single wire, I2C interface device. Digital  
is the way of the future.... :)
